2nd clutch defective

Notes

Check the engine and transmission mounts.

Notes

Inspect shift solenoid valve E for seizure, and the O-rings for wear and damage.

Notes

Inspect the A/T clutch pressure control solenoid valve filter/gasket and the O-rings for wear and damage, and inspect the solenoid valves for seizure.

Notes

Check the 1st and 2nd clutch pressures A/T Pressure Test.

Notes

Check for a clogged orifice in the separator plate. If the orifice is clogged, remove it and clean the separator plate orifice.

Notes

Inspect the clutch piston, the clutch piston check valve, and the O-rings. Check the spring retainer and the retainer seal for wear, damage, and peeling. Inspect the clearance between the clutch end-plate and the top disc. If the clearance is out of tolerance, inspect the clutch discs and the plates for wear and damage. If the discs are worn or damaged, replace them as a set. Inspect the clutch wave-plate height. If the height is out of tolerance, replace the wave-plate. If the discs and the plates are OK, adjust the clearance with the clutch end-plate.

Notes

Check the lock-up shift valve in the regulator valve body for free movement, and check the lock-up shift valve spring for wear and damage.

Notes

Inspect the 1st clutch feed pipe. If the 1st clutch feed pipe is scored, replace the end cover.

Notes

Replace the secondary shaft if the bushing for the 1st clutch feed pipe is loose or damaged.

Notes

Check the 1st accumulator piston, the O-ring, and the springs in the regulator valve body for wear and damage.

Notes

Check the 2nd accumulator piston, the O-ring, and the springs in the servo body for wear and damage.
